The author provides a review of religious life in Vietnamese History. He then argues that Vietnamese spirituality is basically an open spirituality with an open pantheon. Its tolerance makes it easy to acquire different religions in a peaceful way. The core of Vietnamese spirituality is the love for the country and ancestor worship. The love for the country has constituted a “bronze wall” in Vietnamese spirituality that no one is allowed to violate. If anyone tries to break the wall, he will be surely punished despite belonging to religion.
